GRID PLATE FSB BATTERIES.

Application filed Septemher 16, 1921. Serial No. 501,135.

To all wit-0m t l/nag/ concern.: j

lle it known that Gnonon Davis and L irnnuvcn M. SAMUEL, citizens of the United States, residing at New York city, in the county of New York and State ot New York', have invented certain new anduseiul vlmprmfements in Grid Plates for Batteries, of which the following is a specifica-tion.

This invention relates to new and useful iniprovements in grid plates for storage batteries, and the primary object is to pro vide agrid plate of such construction as will cause the ingredient-s of the battery box to more closelyT adhere to said plate, thus affording the most eiiicient results.

.fi further object of the invention resides in -providing a. grid plate provided with diagonally disposed ribs, anda still. further object resides in providing such ribs on both faces' of the plate, the ribs being triangular incross section withtheir apices 'facing inwardly toward one another.

Still another object of the invention resides in providing a device which is simple f anddurable in construction, 'inexpensive to manufacture and one which will be very efficient and useful in operation.V

`With these and other objects in view, our invention consists in the novel Jfea-tures ot construction, combination and arrangement of parts as will be hereinafter referred to and more particularly pointed out in the specification and claims.

In the accompanying drawing forming a part of this application- Figure l is an elevation ot a grid plate constructed in accordance with our inven-k grid `plate which is preferably rectangularin design and may be of any desired thickness. Formed integral with the upper p0rtion thereof adjacent one side edge is a projection 2 through the medium of which the plate may be secured to the lcover ot the battery.

Extending diagonally of the frame work l and having the outer-faces thereof flush with the opposite faces of the ,traine work are two main series of parallel ribs 3 and et. The ribs l are arranged in' staggered re lation to the ribs 3. As stated above, these ribs entend diagonally ot the frame work "l, being cast integral therewith and sa'ulribs'l are connected together by diagonal ribs 5 which extend yin a direction opposite to the direction ot the ribs 3 and 4, asV appears obvious from Figure l of the drawing, 'where it will be seen that the diagonal ribs 5 ar.x composed of short triangular prisms joined together and turned in opposite directions to grip the alternate. ribs ot the two main series. f

The ribs B and are designed triangular in cross section and the apices thereof face inwardly toward one another so as to pro vide adhering or bearing faces on the rib-s which also face inwardly. ln this manner the material within the battery boi: may adhere to the faces ot the ribs. and be securely held to the grid plate. Considerable din".- culty has been encountered heretofore in the use of grid plates, due to the fact that no provision has been made for the retention oi? the material 'to the ribs or other formations on the grid plate, but it willbe seen that with a construction such as we have illus trated and described'in the present application, thisA difficulty will be overcome and tl e maximum eiliciency obtained from the use of such grid plate. IThe diagonal disposi tion of the ribs will greatly assist the particular construction ot said ribs in the retention O the material thereto.

From the foregoing description it will be seen that we have provided a simple, inexpensive and eicient means forcarrying ont the objects of the invention.

Thilo we have particularly described the elements best adapted to perform the functions set forth, it is obvious that various changes in form, proportion and in the minor details of construction may be re-y sorted to without departing from the s i it or sacrilicingany of the principles o invention.

Having thus described our invention, what we claim is:

l. A grid plate comprising a frame, two

main series of parallel ribs extending in line l diagonaldirection across said rame and are' ranged in'staggered relation, and auxiliar ribs eatending transversely to said tirs named ribs, said auxiliary ribs being composed of `joined members that are alternately united With the ribs of said first-named series.

2. A grid plate comprising a trarne, tivo main series of parallel ribs extending in like diagonal direct-ion across said frame and arranged in staggered relation, said ribs be ing triangular in cross section with their apices facing inwardly and With their` bases flushed With the opposite. surfaces of said trarne, and auxiliary ribs extending transversely to said first-named ribs, said auxiliary ribs lbeing composed of joined members that are alternately united with the ribs of said irstfnamed series.

3. A grid plate comprising a traine, two rnain series of parallel ribs extending in like diagonal direction across said frame and arranged in staggered relation, said ribs being triangular in cross section with their apices i'aeing inwardly and with their bases flushed with tire opposite surfaces of said tranne, and auxiliary ribs extending transversely to said tiret-named ribs, said auxiliary ribs being composed of joined triangular prisms that are alternately united with the ribs of said li rst-named series.

fi. A grid plate comprising a frame, two inain series of parallel ribs extending continuously in one diagonal direction only across said frame and arranged, one series Y vv ith respect to the other, to provide uniform spacing of the ribs, and transverse members alternately connecting with the ribs of the tiro inain series of ribs.

A grid plate comprising a trame, tivo main series or parallel ribs extending continuously in one diagonal direction only across said frame and arranged, one series with respect to the other, to provide uniform spacing of the ribs, and transverse connecting members extending continuously across the plate and alternately connecting with the ribs of the two main series of ribs. 6. A grid plate comprising a frame, two iain series of parallel ribs extendingcontinnously in one diagonal directiony only across saidl trarne and arranged, one series `with respect to the other, to provide uniform spacing of the ribs, and serrated transverse connecting ribs for connecting thetivo series of main ribs, the serrations connecting vthe ribs of one series of main ribs, and the ribs or the .other main seriesfof ribs connecting between the serrations of the transverse rib, said serrated ribs being alternately arranged with the serrations standing in opposite directions. y Y

7. A grid plate comprising a frame, two

' main series of parallel ribs extending continuously in one diagonal direction only across the plate, and arranged, one series with respect to the other, to provide uniform spacing of the ribs, and transverse members comprising serrated ribs alternately conf necting with the tivo main series of ribs, and alternately arranged, in which the serrations stand in opposite directions, said arrangement'of main and transverse ribs forming the bounds of oblong open spaces in the face of said grid, said serrations forming end ivallsto said spaces.
